Why do some mobile phones show that nucleic acids have been sampled, while others?

It may be caused by the delay of network update time, or it may be that too many samples are collected, and yours is behind.

If you have a nucleic acid test, it is normal that the health code is not displayed. Sometimes the update is slow and will be displayed in 24 hours.

There are many people doing nucleic acid testing all over the country, almost all of them are full of nucleic acid, and it takes a while for each nucleic acid testing point to upload information. If the effect is slow, don't worry, it is recommended to wait patiently.
